You should proceed as soon as possible to check out the Library of Congress's page on flickr, as announced this morning .
It's an awesome collection of about 3,000 images, of the quality
you'd expect from the world's largest library. It's wonderful to see
them available the same way we expect to share images with each other,
sort of making history less of something living in a museum, and more
of something available, relevant, and even sorted through tags.
